1) Denis Suarez
Denis Suarez was let go by Barcelona in 2015, the club he spent a part of his youth at, training at the La Masia. He eventually went out on loan to Sevilla where had a less than impressive spell after which he made a permanent switch to Villarreal in 2015.
The little playmaker was the heartbeat of the yellow submarines last season helping his club finish in the top four and qualifying for the Champions league. His previous employers were so impressed they eventually signed him back this summer.
Something Barcelona visibly lacked last season was squad depth and Enrique has tried to address that this window by signing players who could perform the squad player role. But Suarez might turn out to be more than just a squad player for Barca this season.
With Iniesta not playing many minutes in pre-season and then being ruled out for the first two weeks of the new campaign Suarez got his opportunity and has taken to the role extremely well.
The Catalans might have just found their successor to Iniesta in Suarez and with the 32-year-old nearing the end of his playing career. The 22-year-old might get more minutes than what even he would have expected this season.
